Question

1) Our first example is the reaction of ethanol, C2H5OH (a component In some gasoline mixtures) with oxygen. When ethanol is burned one molecule of ethanol combines with three oxygen molecules to form two CO, molecules and three H20 molecules. a) Draw two molecular sized models: one for the reactant mixture and one the product mixturel Use different colors or different shading to indicate the identity of the atoms. b) Write the balanced chemical equation for the reaction described. Check your answer with your instructor before proceeding. c) How many molecules of Co, and H2O would be produced when 2 molecules ethanol are consumed? d) How many H,0 molecules are formed, when 9 0, molecules are consumed? Explain how you calculate this by writing an equation! Write an equation using the coefficients as conversion factors! e) 15 ethanol molecules react, how many molecules O, must also react? Explain how you Calculate this by writing an equation! Write an equation using the coefficients as conversion factors! ad Dou....pa single and Dou....pdf MacBook Air

Answer 1

मा 10X I don't have many colour pen su wrote hoeverytie Chemnical formula into Circle. But I you have to use different colour pen or pericil. At four different colour pen or pencil to represent eghool, O2, CO₂ and H2O) C, HE OR + '302 200, + 3H, 0 Bachemical equalition) If a molecules ethand is consumed than 4 molecoftle of con and 6 molecule of H2O is consumed, ( GH5OH + 30% - 200, +370) * 2 3C- Is OH + 6 , + 4 , + C , di According to balanced chimical equation, 3 mole- of 2 is consumed I to give 3 molecule of H₂o. 3 molecule 02 3 3 molecule of H₂O Conversion factor 9 molecule of 0 x 3 molecule of H₂O = 9 molecule of Ko bo s h 3 molecule of of According to balanced equation, 1 molecule of GHS OH (ethanol) react with 3 molecule of Op. Means 1 molecule of C 4504 = 3 molecule of 2 Conversion factor - 15 molecule of C4504 X3 molecule of 45 molecule I molecule of Ghison ! (e
